Question

Factorise - 1)3x+3y+px+py. 2).ax+bx+7a+7b. 3).xy-zx-2y+2z.​

Answer 1

Step-by-step explanation:

1)3x +3y+px+py

=3(x+y)+p(x+y)

=(3+p)(x+y)

2)ax+bx+7a+7b

=x(a+b)+7(a+b)

=(a+b)(x+7)

3)xy-zx-2y+2z

=x(y-z)-2(y-z)

=(x-2)(y-z)

Answer 2

Step-by-step explanation:

1.

3x+3y+px+py

3(x+y)+p(x+y)

(3+p)(x+y)

2.

ax+ bx +7a +7b

x(a+b)+7(a+b)

(x+7)(a+b)

3.

xy+ zx +2y+ 2z

x(y+z)+2(y+z)

(x+2)(y+z)
